WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 718,754, dated January20, 1903.

Application filed October 28,1901. Serial No. 80,314. (No model.)

To 60% whom it may concern:

Be it known that I, WILLIAM GEORGE GIB- BINS a subject of the King ofGreat Britain and Ireland, residing at Leytonstone, in the county ofEssex, England, have invented 1mprovements in Washing-Machines, of whichthe following is a specification.

In the specification of former Letters Patent granted to me, No.638,180, dated November 28, 1899, is described a washing-machinecomprising an oscillating vessel having mounted within it a squeezer,between which and the sides of the vessel the goods are squeezed, andthe arrangement illustrated in said specification is such that While thegoods on one side of the squeezer are being squeezed those on the otherbecome immersed in the cleansingliquid, the movement of which turns themover.

.The present invention has reference to washing-machines of this kind,and according thereto the squeezer is arranged to conform more or lessclosely to one side of the vessel and the goods are placed between itand the other side of the vessel, by which arrangement the goods areallowed greater freedom while being turned by the oscillation of thevessel and the consequent movement of the cleansing liquid.

In some cases it is desirable to squeeze the goods only once during twoor other given greater number of complete oscillations of the Vessel. Toprovide for this, the squeezer is actuated by suitable means in suchwise that it oscillates with the vessel during one oscillation or two ormore consecutive oscillations thereof and is given a tendency tomaintain an attitude approximately corresponding to the upright positionof the vessel or to oscillate reversely to the vessel, so as to squeezethe goods during the next oscillation of the vessel, and so on.

Referring to the accompanying illustrative drawings, Figure 1 shows apower-machine according to the present invention in front elevation, andFigs. 2 and 3 are elevations of the ends thereof. Figs. 4 and 5 arecross-sections on the lines A A, Fig. 1, the machine being shown in adifferent attitude in each. Fig.

6 is a detail sectional view on the line 6 6 of Fig. 5.

1 is the oscillating vessel, which is provided with trunnions 2, restingin bearings 3 on the frame 4 of the machine.

The vessel 1 is formed with an opening 5, through which the goods andcleansing liquid are charged and discharged. The opening is closed by alid 6, secured in place by catches or buttons 7.

The main shaft 8 extends lengthwise of the machine and carries at oneend fast and loose pulleys 9 and 10 and at the other end a crank-arm 11,that is connected by a rod 12 to a toothed segment 13, pivoted at 14 tothe frame 4 and gearing with another toothed segment 15, fixed to one ofthe trunnions 2.

The squeezer 16, which is fixed to a shaft 17, extending throughout thelength of the Vessel 1 and through a suitable gland 18 in one endthereof,is in the form of a perforated brass plate 16, which conformsmore or less closely to the one side wall of the vessel 1. The goods'are placed between the squeezer and the other side wall of the vessel 1.Both the side walls are curved as described in the specification of mybefore-mentioned Letters Patent, so that the liquid in rushing from oneside of the vessel to the other will tend to turn over the goods Whilethey are not being squeezed, so that different surfaces of the goods arepresented to the partition and wall when next squeezed.

The brass squeezerplate 16 is fixed to curved arms 19, projecting fromthe shaft 17, and is faced with longitudinal rubbers or slats 20, thatare secured in place at the required distance apart by a binding-strip21 at each end, which strip is beveled or slopes outwardly, as shown inFig. 6, toward the adjacent end of the vessel 1 in such wise as to tendto push the goods away from the end of the vessel. Opposite the squeezerthe side wall of the vessel 1, which is lined with brass or copper 1*,is provided internally with rubbers or slats 22.

On the shaft 17 is an external arm 24, that is provided with a roller25, which travels over the face of a curved bar 26, that forms a pathwhich is concentric with the center of oscillation of the vessel 1 for aportion of its length and maintains the squeezer 16 close to the oneside of the vessel. Beyond this concentric portion a curved bar 27 ispivoted at 28 to an angular projection on the bar 26, so that it can bemoved into such an attitude that the roller 25 during the oscillation ofthe vessel will travel along the back or outer part of the bar 27, whichthen serves as a cam-path to force outwardly the roller 25, and thusswing the squeezer 16 toward the middle of the vessel 1, relativelyspeaking, so as to squeeze the goods. To prevent shock between theroller 25 and the concentric portion of the bar 26 during the returnmovement of the vessel, this bar is continued around and parallel withthe back of the cam-path 27 when the latter is in its operativeattitude, Fig. 5.

In some cases the cam-path 27 may be pivoted upon the continuation ofthe concentric part of the bar 26, which bar is pivoted at 29 to themachine-framing and is normally held in position by a spring or springs30, but is capable of moving in opposition thereto. The free end of thebar 27 is provided with a stop or link piece 27, which serves to limitits movement relatively to the bar 26. This means enables the squeeze tobe applied to the goods with the required pressure, but allows thesqueezer 16 to yield if the pressure becomes excessive.

For the purpose of moving the bar 27 at the times required to cause thegoods to be squeezed only once during two or other given greater numberof oscillations of the vessel 1 any suitable means may be employed. Inthe arrangement illustrated the shaft 8 carries a pinion 32, that gearswith a wheel 33, provided with a projecting pin or arm 34, adapted topush out of its path the one end of a bent lever 35, pivoted at 35 to alug 35 The other end of the lever 35 extends beneath a pin 35 Fig. 3,projecting from the bar 27. The movement of the lever 35 by the pin 34is thus adapted to raise the nose of the bar 27 to allow the roller 25to pass beneath it; but the pin 34 clears the lever 35, and thusreleases the bar'27 in time to allow it to again fall into itsinoperative attitude as soon as the roller 25 clears the bar 27 duringthe backward oscillation of the vessel 1.

Other means than those described may be employed for causing thesqueezer to oscillate with the vessel during one oscillation or two ormore consecutive oscillations thereof and to maintain an attitudeapproximately corresponding to the upright position of the vessel or tooscillate reversely to the vessel during the next oscillation thereof,and so on.

37 is a dirty-liquid-discharge valve, which can be operated by ahand-lever 38. The vessel 1 can be charged with hot or cold waterthrough the pipes 39 and 40, respectively, which are connected to one ofthe trunnions 2, which is hollow and connected to the well 1 of thevessel 1 by external pipes 41 and 42. 43 is a steam-supply pipe, alsoconnected to the hollow trunnion and is fitted with a pressure-gage 44.

The vessel 1 is fitted at 45 with a safetyvalve and at 46 with a cock toallow escape or admission of air as required.

Washing-machines according to this invention may be variously modifiedand some of my improvements may be employed without others.
